    Why You Should Read This Article     

    For starters, the author starts this article off with a comment that we’ve all heard about target heart rate; “I’m above my target heart rate (don’t forget the infamous “fat-burning zone!).” Jason Karp’s article, Interval Training for the Fitness Professional serves as an excellent resource for personal trainers in regards to the science and implementation of interval training. 
     
    Key points from the article include a comparison of interval training versus long-slow distance training (LSD). Benefits of interval training, as compared to LSD, include the premise that a greater amount of intense work can be accomplished when rest periods are included. Remember back to basic bioenergetics, intensity has a greater affect on fitness level then duration or frequency.  
     
    The article continues to discuss the history and physiology of interval training. The physiological rationale supporting interval training includes greater increase in stroke volume and increased glycolytic and aerobic enzyme activity in active muscles. End result: greater increases in VO2max and lactate threshold.  
     
    Do you want to know how to manipulate the training variables in order to maximize energy specificity and training effect? You’ll have to read this article.
